What we store

This site keeps three values in your browser. All three are needed for it to work, there are no analytics, and nothing is shared with anyone else.

• Your sign-inA token that keeps you signed in. Removed when you sign out.
• Your languageSo the site opens in the language you chose last time, including before any script runs.
• This noticeA flag recording that you have seen the storage notice.

Your account details — your email address and your balances — are held on our servers because the product cannot work without them. Signing out removes the sign-in token from this browser.
